Add Radium

[colinmegill]

Lots of functionality needs stylz... let's do it in radium! i have a branch that preserves the state of the application, which will be used for teaching (the style-less version) so feel free to work off master. I built an input and a button component to start thinking about what I need and it's a hard problem. We cannot anticipate everything someone might want in a button component :/ bunches to talk about.
